A Yiannis is a "pimpin" Greek male. A Yiannis is the coolest person you will ever meet, so treat them well and do as they say.

A Greek name, usually for a strong, handsome male.
Yianni's usually play the bass, but have been known to play the pan flute on occasion (see: Yianni: Master of the Pan Flute).

Full of knowledge, and is secretly a ninja. (but don't tell anybody, its all very hush hush).
